• Performing a fuzzy search may retrieve terms with similar spellings: bo ((sach thu) OR (sach thue)) hang ma hoi. hieu va cham cuu gia thanh van ((cua te) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: bo ((sach thu) OR (sach thue)) hang ma hoi. hieu va cham cuu gia thanh van ((cua te) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "bo ((sach thu) OR (sach thue)) hang ma hoi. hieu va cham cuu gia thanh van ((cua te) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: bo ((sach thu) OR (sach thue)) hang ma hoi. hieu va cham cuu gia thanh van ((cua te) or (cuu tre))*.
